When thinking about security within a MySQL installation, you should consider a
wide range of possible topics and how they affect the security of your MySQL
server and related applications:
* General factors that affect security. These include choosing good passwords,
not granting unnecessary privileges to users, ensuring application security
by preventing SQL injections and data corruption, and others. See
Section 6.1, “General Security Issues”.
* Security of the installation itself. The data files, log files, and the all
the application files of your installation should be protected to ensure that
they are not readable or writable by unauthorized parties. For more
information, see Section 2.9, “Postinstallation Setup and Testing”.
* Access control and security within the database system itself, including the
users and databases granted with access to the databases, views and stored
programs in use within the database. For more information, see Section 6.2,
“Access Control and Account Management”.
* The features offered by security-related plugins. See Section 6.4, “Security
Components and Plugins”.
* Network security of MySQL and your system. The security is related to the
grants for individual users, but you may also wish to restrict MySQL so that
it is available only locally on the MySQL server host, or to a limited set of
other hosts.
* Ensure that you have adequate and appropriate backups of your database files,
configuration and log files. Also be sure that you have a recovery solution
in place and test that you are able to successfully recover the information
from your backups. See Chapter 7, Backup and Recovery.
Note
Several topics in this chapter are also addressed in the Secure Deployment
Guide, which provides procedures for deploying a generic binary distribution of
MySQL Enterprise Edition Server with features for managing the security of your
MySQL installation.
